Description
Die Erfindung betrifft ein Brühgerät in einer im Oberbegriff des Anspruches 1 erläuterten
Ausbildung.The invention relates to a brewing device explained in the preamble of
Ein Brühgerät ist bereits aus der EP-B-0 663 803 bekannt. Bei dieser Konstruktion ist die die Filtervorrichtung in ihrer den Getränkesammelbehälter überfangenden, eingeschwenkten Gebrauchslage sichernde Rückhaltevorrichtung manuell entriegelbar. Hierzu ist an der vorderen Geräteseite in Höhe des sich zwischen der Filtervorrichtung und dem diese überdekkenden Gehäuseabdeckteil befindenden Spaltes ein Betätigungsglied vorgesehen. Beim Aufbrühen von Kaffee oder Tee erwärmen sich Filtervorrichtung und Gehäuseabdeckteil und insbesondere das im Bereich des Spaltes vorgesehene Betätigungsglied der Rückhaltevorrichtung nicht nur beträchtlich, sondern diese Teile beschlagen auch mit Kondensat. Der Gebrauch des im Dampfbereich liegenden heißen Betätigungsgliedes der Rückhaltevorrichtung zum Entriegeln und Ausschwenken der Filtervorrichtung ist deshalb unmittelbar nach einem Brühvorgang zunächst kaum möglich.A brewing device is already known from EP-B-0 663 803. With this construction, it is the Filter device in its swung-in overlapping the beverage collecting container Retaining device securing the position of use can be unlocked manually. This is at the front Side of the device at the level between the filter device and the one covering it An actuator is provided in the housing cover part of the gap. At the Brewing coffee or tea will heat up the filter device and the housing cover and in particular the actuator of the restraint device provided in the area of the gap not only considerably, but these parts also fog up with condensate. The Use of the hot actuator of the restraint located in the steam area to unlock and swing out the filter device is therefore immediately after a brewing process is hardly possible at first.
Aus der DE-U-89 12 802 ist ein Brühgerät der eingangs beschriebenen Art bekannt, wobei an der Oberseite des Gehäuseabdeckteils ein zum Öffnen der Filtervorrichtung ausgebildetes Betätigungsglied angeordnet ist, welches zum Entriegeln der Filtervorrichtung von oben her durch Handkraft betätigt werden muß. Dabei wird die Filtervorrichtung mittels freigegebener bzw. ausgelöster Federkraft in einen bestimmten Ausschwenkwinkel überführt.From DE-U-89 12 802 a brewing device of the type described above is known, wherein on the top of the housing cover part designed to open the filter device Actuator is arranged, which for unlocking the filter device from above must be operated by hand. The filter device is released by means of or triggered spring force transferred to a certain swivel angle.
Hier setzt nun die Erfindung ein. Es liegt ihr die Aufgabe zugrunde, ein Brühgerät mit den
Merkmalen des Oberbegriffes von Anspruch 1 so zu verbessern, daß unmittelbar nach Beendigung
eines Brühvorgangs ein einfaches Öffnen seiner Filtervorrichtung möglich ist, ohne
Gefahr zu laufen, bei der hierzu notwendigen Handhabung des Betätigungsgliedes der
Rückhaltevorrichtung sich die Finger zu verbrennen.This is where the invention begins. It is based on the task of a brewing device with the
Features of the preamble of
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches
1 gelöst. This object is achieved by the characterizing features of the
Damit befindet sich das Betätigungsglied in einem sich nur unwesentlich erwärmenden Bereich bzw. an einer Stelle außerhalb des Dampfaustrittsbereichs am Brühgerät, so daß das Öffnen der Filtervorrichtung für den Benutzer angenehm zu bewerkstelligen ist.The actuator is thus in an area which heats up only insignificantly or at a point outside the steam outlet area on the brewer, so that the Opening the filter device for the user is pleasant to do.
Die Rückhaltevorrichtung kann hierbei beliebig ausgebildet sein. Dementsprechend kann auch deren Betätigungsglied an jeder beliebigen Stelle am Gehäuse vorgesehen und sein und ist vorzugsweise in Art eines Bedienknopfes gestaltet.The restraint device can be of any design. Accordingly, also provided the actuator at any point on the housing and be and is preferably designed in the manner of an operating button.
Mit Vorzug zu gebrauchende Anordnungen des Betätigungsgliedes sind dabei in den Ansprüchen 2 und 3 erläutert, die den Vorteil bieten, die Rückhaltevorrichtung, technisch einfach konzipiert, mechanisch auszulegen und im oberen Gehäuseteil bzw. im Gehäuseabdeckteil günstig unterbringen zu können.Arrangements of the actuator to be used with preference are in the claims 2 and 3 explains that offer the advantage of the restraint device, technically simple designed to be designed mechanically and in the upper housing part or in the housing cover part to be able to accommodate cheaply.
Dabei ist es zweckmäßig, die Rückhaltevorrichtung als Gesperre vorzusehen, wobei es zu bevorzugen ist, dasselbe als Grenzkraftgesperre auszulegen. Dies bietet den Vorteil, daß auch ein unsachgemäßes Öffnen bzw. Ausschwenken der Filtervorrichtung von Hand anstatt durch Betätigung des Betätigungsgliedes möglich ist, ohne die Rückhaltevorrichtung zu beschädigen.It is expedient to provide the restraint device as a locking mechanism, whereby it is too prefer to interpret the same as a limit force lock. This has the advantage that also improper opening or swinging out of the filter device by hand instead is possible by operating the actuator without damaging the restraint.
Die Funktion der mechanisch ausgelegten Rückhaltevorrichtung kann bspw. derart sein, daß sie ausschließlich gegen die Wirkung der Schwenkvorrichtung arbeitet, die, als von der Rückhaltevorrichtung unabhängige Baueinheit, versucht, die Filtervorrichtung ständig aus ihrer Gebrauchsstellung herauszuschwenken.The function of the mechanically designed restraint device can, for example, be such that it works exclusively against the action of the swivel device, which, as of the Restraint device independent unit, tries to keep the filter device off to swing out their position of use.
Eine derart arbeitende Rückhaltevorrichtung ist in zu bevorzugender Ausführungsform in den Ansprüchen 5 bis 9 erläutert, wobei eine Ausgestaltung nach Anspruch 7 mit einfachen Mitteln deren Wirkungskraft als Grenzkraftgesperre ermöglicht.Such a retaining device is in a preferred embodiment in the Claims 5 to 9 explained, wherein an embodiment according to claim 7 with simple means whose effectiveness as a limit force lock enables.
Ein weiteres Funktionsprinzip der Rückhaltevorrichtung kann darin bestehen, auf die Erzeugung
eines permanent auf die Filtervorrichtung einwirkenden Schwenkmoments zu verzichten
und demgemäß die Schwenkvorrichtung in die Rückhaltevorrichtung zu integrieren. In
vorteilhafter Weise läßt sich dies gemäß den Ansprüchen 10 und 11 bewerkstelligen. Another principle of operation of the restraint device can be based on the generation
to dispense with a pivoting moment permanently acting on the filter device
and accordingly to integrate the swivel device into the restraint device. In
this can advantageously be accomplished according to

Wie Fig. 1 zeigt, weist die Kaffeemaschine ein aus Kunststoff bestehendes Gehäuse 10 auf,
das im Querschnitt vorzugsweise ringsegment- bzw. nierenförmig ausgebildet ist und eine
größere Höhe als Breite aufweist. An das untere Gehäuseende ist ein vorzugsweise kreisförmiger
Gehäusefuß 12 angeformt, in den eine Warmhalteplatte 14 integriert ist, auf die
eine den aufzubrühenden Kaffee aufnehmende Kaffeesammelkanne abstellbar ist.As shown in FIG. 1, the coffee machine has a
Der obere Teil des Gehäuses 10 bildet einen durch einen aufklappbaren Deckel 16 verschließbaren
Wasserbehälter 17, der bodenseitig mit einer im Gehäusefuß 12 angeordneten,
nicht gezeigten, an sich bekannten Heizeinrichtung verbunden ist.The upper part of the
Erhitztes Wasser wird in bekannter Weise über eine gehäuseinnere Steigleitung in eine gehäuseoberseitig vorgesehene Auslaufkammer zugeführt, aus der es in eine als Ganzes mit 18 bezeichnete Filtervorrichtung gelangt.Heated water is transferred in a known manner via a riser inside the housing to the top of the housing provided outlet chamber, from which it into a whole with 18 designated filter device arrives.
Die nicht dargestellte Auslaufkammer befindet sich in einem auf das Gehäuse 10 fest aufgebrachten
Gehäuseabdeckteil 20, das die Filtervorrichtung 18 in ihrer sich oberhalb der Kaffeesammelkanne
befindenden Gebrauchslage scheibenartig überdeckt.The outlet chamber, not shown, is located in a housing that is firmly attached to the
Die Filtervorrichtung 18 weist ein vorzugsweise tassenförmiges Filtergehäuse 22 auf, in das
zum Kaffeeaufbrühen eine Filtertüte einsetzbar ist.The
Um das Einsetzen bzw. die Entnahme einer Filtertüte in das Filtergehäuse 22 bzw. aus diesem
zu ermöglichen, ist dasselbe relativ zum Gehäuseabdeckteil 20 um eine gehäusefeste,
vertikale Schwenkachse 24 aus seiner Gebrauchslage in eine in Fig. 1 gezeigte Bedienlage
horizontal verschwenkbar, in der es von oben frei zugänglich ist.To insert or remove a filter bag into or from the
Wie aus den Figuren 6 und 7 ersichtlich ist, befindet sich die Schwenkachse 24 im oberen
Gehäusebereich und nahe der linken Gehäuseseitenwand 10' innerhalb einer Wandeinbuchtung
25 bzw. seitlich des Wasserbehälters 17.As can be seen from Figures 6 and 7, the
Mit 26 ist als Ganzes eine Schwenkvorrichtung bezeichnet, die im Gehäuse 10 vorzugsweise
unterhalb des stationären Gehäuseabdeckteils 20 vorgesehen ist. Diese wirkt auf einen
die Filtervorrichtung 18 tragenden und auf der Schwenkachse 24 gelagerten Träger 28 ein
(siehe Fig. 6) und versucht, die Filtervorrichtung 18 ständig in ihrer ausgeschwenkten Bedienlage
zu halten (Fig. 1). Dies wird z.B. mittels eines in der Gehäusevorderwand 10" horizontal
verschiebbar geführten, am Träger 28 anliegenden Stößels 29 bewerkstelligt, der von
einem vorgespannten Kraftspeicher, vorzugsweise in Form einer gehäusefesten Blattfeder
30, beaufschlagt ist. Als Kraftspeicher könnte auch eine auf der Schwenkachse 24 sitzende
Drehfeder oder eine sich einerseits am Stößel und andererseits an einem Gehäuseteil abstützende
Druckfeder vorgesehen sein.A swivel device is designated as a whole, which is preferably in the
Wie aus den Figuren 6 und 7 ersichtlich ist, ist der Träger 28 in etwa L-förmig ausgebildet,
wobei dessen längerer Schenkel 28' vom Stößel 29 beaufschlagt ist, während dessen kürzerer,
auf der Schwenkachse 24 gelagerter Schenkel 28" zugleich ein Verschlußteil bildet,
durch das die Wandeinbuchtung 25 in der Gebrauchslage der Filtervorrichtung 18 seitlich
abgedeckt wird.As can be seen from FIGS. 6 and 7, the
Der Filtervorrichtung 18 ist vorzugsweise innerhalb des Gehäuseabdeckteils 20 eine als
Ganzes mit 32 bezeichnete, in ihrer Funktion von der Schwenkvorrichtung 26 unabhängige
Rückhaltevorrichtung zugeordnet, durch die die Filtervorrichtung 18 nach Einschwenken in
ihre Gebrauchslage in dieser selbsttätig festgelegt wird.The
Diese Rückhaltevorrichtung 32 ist zur Freigabe bzw. zum selbsttätigen Ausschwenken der
Filtervorrichtung 18 mittels eines Betätigungsgliedes 34 manuell betätigbar, das vorzugsweise
in Form eines Druckknopfes vorgesehen ist. Dieser Druckknopf 34 ist an der Kaffeemaschine
außerhalb des Bereiches eines Spaltes 33 positioniert, der sich in der Gebrauchslage
der Filtervorrichtung 18 zwischen dieser und dem Gehäuseabdeckteil 20 befindet. Dadurch
wird vermieden, daß der Druckknopf 34 von Dampf und Kondensat beaufschlagt werden und
sich dadurch unangenehm erwärmen kann.This retaining
Der Druckknopf 34 ist im Bereich des hinteren Endes des Gehäuseabdeckteils 20 in einem
Durchbruch seines oberen Wandteils 20' auf einem vertikalen, gehäusefesten Führungszapfen
36 verschiebbar geführt und stützt sich auf einem Hebelarm 38' eines doppelarmigen
Hebels 38 ab, der um eine horizontale Achse 39 verschwenkbar ist, und dessen anderer
Hebelarm 38" mit der Filtervorrichtung 18 zu deren Festlegung zusammenwirkt. Teile der
Rückhaltevorrichtung 32 und der Filtervorrichtung 18 bilden dabei gemeinsam ein Rastgesperre.The
Der Hebelarm 38' stützt sich auf einer vorgespannten Druckfeder 40 ab, während der Hebelarm
38" am freien Ende ein Sperrelement in Form einer von diesem nach unten abragenden
Nase 42 trägt, der im oberen Randbereich der Filtervorrichtung 18, zur Rückhaltevorrichtung
32 benachbart, einer nach oben und entgegen der Ausschwenkrichtung der Filtervorrichtung
18 bzw. nach hinten offenen Rastausnehmung 44 zugeordnet ist.The lever arm 38 'is supported on a
Wie aus Fig. 2a ersichtlich, ist der der Rückhaltevorrichtung 32 benachbarte und in verrastetem
Zustand der Filtervorrichtung 18 von der Nase 42 des Hebels 38 hintergriffene
Wandteil 46 der Rastausnehmung 44 unter einem Winkel α von vorzugsweise 15 bis 30°
nach oben, außen gerichtet, wodurch die Teile 22, 38 ein einseitig kraftschlüssiges Grenzkraftgesperre
bilden, welches sicherstellt, daß bei unsachgemäßem Ziehen am Filtergehäuse
22 sich das Rastgesperre über die durch den Wandteil 46 definierte, schiefe Ebene der
rückseitig offenen Rastausnehmung 44 selbsttätig löst, die Filtervorrichtung 18 dadurch freigibt
und so eine Beschädigung der sich miteinander in Eingriff befindenden Teile des Gesperres
vermieden wird.As can be seen from FIG. 2a, that of the
Eine Nasenschrägfläche 43 stellt hingegen sicher, daß beim Einschwenken der Filtervorrichtung
18 in ihre Gebrauchslage diese an dem Wandteil 46 der Ausnehmung 44 aufgleiten
und den Hebel 38 entsprechend auslenken kann.An
Der Hebel 38 nebst Gehäuse 10 und Filtervorrichtung 18 sind vorzugsweise durch Formteile
aus Kunststoff gebildet. Der vorzugsweise im Querschnitt U-förmige Hebel 38 ist dabei zwischen
zwei vom Boden 47 des Gehäuseabdeckteils 20 aufragenden Lagerböcken 48 gelagert,
von denen in den Figuren 2 und 3 einer ersichtlich ist. In diese Lagerböcke 48 ist oben
jeweils eine vorzugsweise offene Lagerschale eingeformt, die jeweils einen am Hebel 38
seitlich angeformten, die Hebellagerachse 39 definierenden Lagerzapfen 50 (siehe Fig. 4)
aufnehmen.The
Um die Lagerzapfen 50 in den offenen Lagerschalen zu sichern, ist der Hebel 38 mit einem
zur Lagerachse 39 symmetrisch vorgesehenen, nach oben über diesen vorstehenden hökker-
bzw. stegartigen Ansatz 52 versehen, der bis nahe an den oberen Wandteil 20' des Gehäuseabdeckteils
20 heranreicht und dessen obere Stirnfläche 54 auf einem Radius der Hebelschwenkachse
39 liegt.In order to secure the
Der zwischen den U-Schenkeln 35 und 37 des Hebels 38 geführte Druckknopf 34 hat bspw.
mit einem Außenumfangsbund 34' (siehe Fig. 4) Linienberührung mit jeweils einer Schenkeloberkante,
so daß bei vertikaler Beweglichkeit des Druckknopfes 34 eine Schwenkbewegung
des Hebels 38 erfolgt.The
Fig. 7 veranschaulicht eine konstruktive Lösung, bei der die der Filtervorrichtung 18 gehäuseseitig
zugeordnete Rückhaltevorrichtung als Ganzes mit 56 bezeichnet ist, die mit der als
Ganzes mit 58 bezeichneten Schwenkvorrichtung eine Baueinheit bildet.Fig. 7 illustrates a constructive solution in which the
Teile der Kaffeemaschine, die denjenigen der vorstehend erläuterten Maschinenkonstruktion gleichen, sind mit gleichen Bezugszahlen bezeichnet.Parts of the coffee machine that those of the machine construction explained above same, are designated with the same reference numerals.
